to add to this I have fallen in love with using this thing:

Specifically you will want the HP one, its 600psi instead of 300psi and better made. But man it works for washing the car. Its half has powerful as a real pressure washer which, for me, is perfectly fine. If you need to scrub concrete you just have to get closer, so the job takes longer, but for washing the car its a HUGE help. There is a foam cannon you can attach to it as well which works well.
Im reminded because I just, over lunch, prepped the car for a real bath after work. Sprayed the brake dust off the wheels and got the bugs off the front. So that way this afternoon its just spray, foam, wipe (with a mitt to just get good soapy coverage), rinse, then hit it with leaf blower and then microfiber.
So much easier than messing with a full pressure washer rig.
